NAME

Net::FluidDB - A Perl interface to FluidDB

SYNOPSIS

 use Net::FluidDB;

 # Predefined FluidDB client for playing around, points
 # to the sandbox with user test/test
 $fdb = Net::FluidDB->new_for_testing;
 $fdb = Net::FluidDB->new_for_testing(trace_http => 1);

 # FluidDB client pointing to production
 $fdb = Net::FluidDB->new(username => 'username', password => 'password');

 # FluidDB taking credentials from environment variables
 # FLUIDDB_USERNAME and FLUIDDB_PASSWORD
 $fdb = Net::FluidDB->new;

 # Content-MD5 headers with checksums for requests with payload
 $fdb = Net::FluidDB->new(md5 => 1)

 # Resource getters
 $object     = $fdb->get_object_by_id($id, about => 1);
 $object     = $fdb->get_object_by_about($about);
 $ns         = $fdb->get_namespace($path, description => 1);
 $tag        = $fdb->get_tag($path, description => 1);
 $policy     = $fdb->get_policy($user, $category, $action);
 $permission = $fdb->get_permission($category, $path, $action);
 $user       = $fdb->get_user($username);

 # Object search
 @ids = $fdb->search("has fxn/rating");

USAGE

Class Methods

Net::FluidDB->new(%attrs)

Returns an object for communicating with FluidDB.

This is a wrapper around LWP::UserAgent and does not validate credentials in the very constructor. If they are wrong requests will fail when performed.

Attributes and options are:

username

Your username in FluidDB. If not present uses the value of the environment variable FLUIDDB_USERNAME.

password

Your password in FluidDB. If not present uses the value of the environment variable FLUIDDB_PASSWORD.

protocol

Either 'HTTP' or 'HTTPS'. Defaults to 'HTTP'.

host

The FluidDB host. Defaults to fluiddb.fluidinfo.com.

md5

If this flag is true requests with payload get a Content-MD5 header with a checksum.

trace_http_requests

A flag, logs all HTTP requests if true.

trace_http_responses

A flag, logs all HTTP responses if true.

trace_http

A flag, logs all HTTP requests and responses if true. (Shorthand for enabling the two above.)

Net::FluidDB->new_for_testing

Returns a Net::FluidDB instance pointing to the sandbox with "test"/"test". The host of the sandbox can be checked in the package variable $Net::FluidDB::SANDBOX_HOST.

Instance Methods

$fdb->username

$fdb->username($username)

Gets/sets the username.

$fdb->password

$fdb->password($password)

Gets/sets the password.

$fdb->protocol

$fdb->protocol($protocol)

Gets/sets the protocol, either 'HTTP' or 'HTTPS'.

$fdb->ua

Returns the instance of LWP::UserAgent used to communicate with FluidDB.

$fdb->user

Returns the user on behalf of whom fdb is doing calls. This attribute is lazy loaded.
